A unicorn is a fun and magical costume that’s perfect for birthday parties and Halloween. Unicorn headbands are easy to make and they are great party favors for a little kid’s birthday party or for everyday dress-up play. Wearing a horn is the key to a good unicorn costume, and adding other elements like ears and a tail will help complete the outfit.

Steps

Method 1 of 4: Transforming a Hoodie into a Unicorn Costume

1

Assemble your supplies. Get a hoodie in your desired color (pink, purple or white will work well). You’ll also need pieces of felt in complementary colors, such as white and pink, as well as some cotton stuffing, which is available at your local fabric or craft supply store.

You’ll also need a sharp pair of scissors, sewing machine or needle and thread, and some pins.

Alternately, you can use a glue gun to attach pieces to the hoodie, instead of sewing them on.

2

Cut felt pieces for the mane. Cut equal numbers of felt, measuring 9 inches long and 2 inches wide. Cut enough pieces to cover from the crown of the hood (about 4” from the front top of the hood) to the bottom hem of the hoodie, laying them lengthways.[1]

3

Attach the mane felt pieces to the hoodie. Fold each felt piece into a circle by joining the short ends together. Overlap the pieces by about one inch. Pin these pieces along the backside of the hoodie.

Use a zigzag stitch on your sewing machine to attach the pieces to the hoodie. Alternately, sew this by hand.

You can also attach these pieces with safety pins on the inside of the hoodie. This will enable you to reuse the hoodie without the unicorn features.[2] Cover the safety pins with duct tape to ensure that the costume wearer won’t get poked by pins if they accidentally open up.

4

Cut the mane felt pieces. Once the mane is attached to the hoodie, cut the looped ends with your scissors, making 3 cuts lengthways on each loop. Then cut each loop open so that you have a frayed-looking mane.

5

Make the ears. Cut two triangles of felt in one color such as white, and cut two triangles in another color such as pink. The white triangles should be larger than the pink triangles, and the white ones should be about the size of the palm of your hand.

Layer a white and pink triangle together, with the white on the bottom. Sew the two triangles together by sewing along the center. Do the same for the other set of triangles.

6

Stitch the ears to the hoodie. Place the ears on each side of the mane a couple of inches back from the front edge of the hood. Pin them in place. Try on the hoodie to check for placement. Stitch them in place using a needle and thread, or use safety pins on the inside of the hood to attach them.

7

Make the horn. The horn is the essential part of the costume. Cut a large triangle out of white felt. The triangle should be a couple of inches longer than the length of the hood. Fold the triangle together lengthwise and stitch it closed. This will form the cone shape of the unicorn horn.

Fill the horn with cotton stuffing. Use a knitting needle or pencil to push stuffing into the point of the horn. Make sure the horn is evenly stuffed but not overstuffed.

8

Attach the horn to the hoodie. Pin the horn in place on the very top center of the hoodie. Try on the hoodie to check for placement. Take the hoodie off, and using a matching color of thread, hand stitch the horn in place.

Use a whipstitch to secure the horn in place. To do a whipstitch, poke the needle through the underside of the hoodie and bring it up through the hoodie and through the horn felt. Then poke the needle through the hoodie just under the base of the horn and back up through the felt. This makes a loop of thread that will secure the horn in place.[3] Stitch all around the base of the horn.

9

Add a tail. Cut long, thin pieces of felt that will extend down to the knees when your costume is on. These can be a combination of colors. Gather the pieces together at one of the short ends and stitch them to the center back base of the hoodie.

10

Complete the costume. Put on the hoodie and zip it up. Complete the costume with matching or complementary pants or leggings, shoes, and gloves.

You can also paint your face to look like a unicorn.

Method 2 of 4: Making a Dreamy Unicorn Costume

1

Gather your supplies. Create a unicorn costume with a tank top, headband and a tulle skirt. Repurpose an old tank top in a bright or pastel color. Buy about 2 yards of tulle in a preferred color. You’ll also need a length of elastic to go around your waist, a headband, rhinestones, and a glue gun.[4]

2

Decorate your top. Assemble rhinestones on your tank top along the neckline and extending downward in a V pattern. Use a hot glue gun to attach the rhinestones to the tank top.

3

Make a tulle skirt. Measure a piece of elastic to fit around your waist comfortably. Sew the two ends together so that it makes a circle. Cut lengths of tulle that will be twice as long as your desired skirt length.

Fold each strip of tulle in half. Tie these strips onto the elastic circle. The more strips you add to the elastic, the fuller and fluffier the skirt will be.

4

Make a unicorn headband. Cut a large triangle out of felt. Wrap it into a cone shape and glue the cone closed. Attach this cone to a headband using a hot glue gun.

You can also use a cone-shaped piece of foam, available from a craft supply store. Wrap tulle around the cone and glue in place with the hot glue gun.[5]

Method 3 of 4: Making a Unicorn Headband

1

Gather your supplies. Fashioning a unicorn horn and ears to a headband will make an instant costume. For this project, you’ll need a headband, felt (white and pink), cotton stuffing, thick gold thread and a glue gun. These supplies are available at a fabric or craft supply store.

You can also use a piece of ribbon or elastic instead of the headband, although it might not stay on your head as well.[6]

2

Make the horn. Cut out a large triangle from a piece of white felt. The triangle should be about the same height as the headband, and the bottom end of the triangle should be about 2-3 inches in diameter.

Roll the felt into a conical shape. Use the hot glue gun to glue the horn in place.[7] You can also sew the horn into a conical shape.

Stuff the horn with cotton stuffing. Use a knitting needle or a pencil to poke the stuffing into the tip of the horn.

3

Wrap gold thread around the horn. To make the horn look more magical, wrap the thick golden thread around the horn in a spiral pattern. Glue one end of the thread to the top of the horn and wind the thread around the horn over and over until you reach the bottom of the horn. Glue the horn to the bottom of the horn.

Tighten the gold thread slightly so that the horn is squeezed a little bit.

4

Attach the horn to the headband. Cut out a circle of felt just slightly larger than the bottom of the horn. Place the headband in between the horn and the felt circle. Glue the circle to the horn and the headband.

5

Cut out the ears. Cut out two sets of the bottom layer of the ears. Use white felt in double-layer tear shape, approximately 3 inches long. Keep the bottom of the double layer uncut, so that when you unfold the layers, you have two tear shapes reflecting each other. Cut two more ears from the pink felt, also in the tear shape, in single layers. These should be slightly smaller than the white ears.[8]

6

Attach the ears to the headband. Wrap the white ears around the headband on either side of the unicorn horn. Glue the bottom folded part onto the underside of the headband’s top. Glue the ear tops together. Add the pink ears onto the white ears, facing forward, and glue them in place.

Method 4 of 4: Throwing Together a Last Minute Unicorn Costume

1

Make a unicorn horn. Roll up a piece of paper into a cone. Trim the bottom of the cone so that it will sit flat on your head. Tape or staple a ribbon or elastic to the bottom of the horn. Tie the horn to your head.[9]

Decorate the horn with markers, crayons, glitter glue or stickers.

You can also use a gold or silver party hat to make a horn. Unroll the party hat and cut out a 1-2 inch section from it. Re-roll the hat and tape it into cone shape. Tape or staple an elastic onto the bottom of the hat.

Make a tail. Use curling ribbon or yarn in pastel colors to make a tail. Cut several pieces of ribbon or yarn to reach from your waist to your knees. Tie these pieces together at one end and pin or tie them to the back of your pants.[10]

4

Complete the outfit. Wear black or brown shoes to stand in for hooves. You can also wear black or brown gloves as your front hooves.
